I recently changed the defective & worn tracking disc in my 2006 heater flap solenoid motor

i used a donor part from an Avensis part number AE063700-8610 (off eBay) for £20

 

Here’s a YouTube video I’ve put together of how I went about changing it

Did mine today. Took 4 hours . Couldn't have done it without the help of this video. Will try to put pic of disc I took out of 

Happy New Year to you all. Having watched the You Tube clip I purchased a secondhand module from an Avensis 2003 and just had to find the time to strip the parts from our Alphard. I have not had any heat for the past three months even when I changed the temperture settings. Changed the coolant and thermostate as well as the radiator cap, had these done over the past few months hoping to sort the problem out.Yesterday I found the time thinking it would take time to complete the job. Got as far as stripping the centre console out, got to the module and unplugged it and moved the rods and heard a click. Decided to check to see if I had any heat before I went any further, stroke of luck and I now have heat on all modes. Thanks to Goldstar for the How to Guide it made all the difference doing the strip down.
